    Default low note and hi note horns for 57

    Does anyone out there know why the model numbers are different for pontiac vs chevy? are the pitches adjusted differently?

    Greetings, Rod - Although your post is old, I thought it couldn't hurt to reply. I have several sets of horns, some trumpet style (most from '60s Pontiacs). If you are interested (the least bit), feel free to contact me at, or by calling 619-442-2800 (CA). My POCI # is 24380. Thank you!
